This inventionrelates to door holders and particularly such devices ofthe type wherein means are provided for securing the door in openposition at a predetermined limit of swing.

6 One object of the invention is a novel and improved door holdermechanism which is readily adaptable to both right and left hand doors,which optionally automatically locks the door in the open ,position, andwhich protects the door and mecha- I 'nism against undue shocks andstrains at all times by permitting'cushioned movements of the doorinboth directions. A further object of the invention is a door holdermechanism of this general character which is characterized by thesimplicity of itsparts and mechanism, and by its ruggedness inconstruction and dependability in operation.

The several features whereby these and other objects may be attainedwill be readily understood'frorn the following description and,accompanying drawings in which: s s

I have illustrated my invention as embodied in s a pair of ears or jaws9 and iii projecting outward- "lyfrom the plate right angles thereto. 7The arm 2 is in the form of a heavy bar reduced in thickness at itsouter end to form a tang or plate H which is supported between thejaws 9,and iii of the bracket 7 and is pivotally fastened 1 theretobynieans'of a removable pintle it pass- 'a door holding mechanismcomprising a pair of,

through registering openings formed inthe, jaws?) and lilandthe tang il.The pintle l3 hasa' head it which] is countersunk into a recess formedin the'jaw 9, and the pintle is anchored in position by means of a lockscrew 29 which is screwed into the jaw 9 and engaging a niche formedthehead i l. The tang H is provided with a stop lug or heel l5 on onesidethereof, thislughaving an abutting face l5' which engages tne face ofthe plate 8 and limits in one dirctioflthe angular movement of the bar 2h f i t O e plate and d oor. 'Ifhebracket lf issymnietricallyconstructed, that is, the jaws SfaLri'd ii) are disposed at right anglesto the plate land the plate 8 projects to both sides thereof in theplanesof the jaws; and, as will hereinafter appear, the door holdingmechanism may be readil'yada'pted to either a righthand or lei'thandswinging doer by merely reversing the position of' the'bar 2 withrespect to its top and bottom fa'c'es or by turning it over with the lugor stop ltfdisDOSe'd onthe opposite side, in whichreverse positioii'thelug: engages the opposite projecting side 'of the plate Set the limitof angular movet;

There is a single locking means cooperating with thi'sreversiblebar andstop lug and this comprises a hand'ma'nipulated locking plunger it whichis cjarrledby the jaw ill of the bracket and cooperates witha recess itformed in the tang or plate II; This. plunger is located eccentricallywith respectto the pivotalaxis of pintle it and also symmetricallywith'respect to the projecting sides of the plate 8, that is in theplane including the axis of the pintle and disposed atrlght angles tothe plate 8 in order to obtain the symmetrical disposition thereof, andin the particular embodiment shown this plunger is located on,theopposite side of the pintle from the plate 8.

V The plunger I8 is upported in the depending tubular housing 20, thelatter being integrally formed with the lower jaw IQ of the bracket, andis, normally urged upwardly through an opening 21' formed in'the lowerjaw Ill and registering with thetubular housing. Plunger i8 is normal-1y urgedupwardly by spring 22 held betweencollar ZS'of plunger IB andretaining washer 24, the washer t lloosely surrounding the plunger andbeingheld within the housing by a suitable bushing 25 which is screwthreadedly attached to the housing, Bushing 25 is provided with grooves26 in which a pin 2 7 of latching plunger I8 slides when inoperativeposition, the plunger being placedin operative position when the pin 21is aligned with the grooves 26.

The recess [9 formed in the tang H of the bar 2 is so positioned thatwhen the stop lug [5 engages the plate 8 or the door the plunger [8 isin register therewith. The stop lug l5 projects outwardly from tang IIand is offset from the center line of the arm 2 and the abutting face l5of lug l 5 is disposed at an acute angle to the center line 39 of thebar 2. The locking recess or opening I9 is likewise offset from the'bar2 and with the lug iii in engagement with the door or plate 8 the centerline of recess I9 is disposed in the plane passing through the axis ofthe pintle l3 and at right angles to the plate 8. In the particularembodiment shown, namely, where the plunger I8 is disposed on theopposite side of the pintle I3 from the plate 8, the recess [9 isoffsetv from bar 2 to the opposite side from the lug l5. The inner endsof the arms I and 2, as above indicated, are joined together forrelative swinging movements. The inner end 40 of the arm I 1 is offsetfrom the main body thereof (Fig. 3') and is provided with a fiat bearingsurface cooperating with a similar flat bearing surface on the end 4| ofthe bar 2, the end 4i being slightly reduced in thickness from thethickness of the bar 2. The ends 40 and 4| are maintained in bearingengagement by means of a bolt 42 passing through registering openingsformed therein, but this bolt 42 takes no part in the longitudinalstrain or force placed upon the two bars I and recess 43 when the twobars are held together.

These'cooperating female and maleparts are of comparatively shallowdepth and are capable of transmitting the maximum strains put thereuponwith the desired factor of safety. The end M of the bar 2 is, as aboveindicated, made symmetrical on both its upper and lower sides so thatmerely by reversing the positionthereof it may be adapted to either aright hand or left hand door. For this purpose the correspondingcooperating strain transmitting member on the end 4| of the bar 2 isduplicated on both sides thereof and accordingly the bar 2 is providedon one side with the cooperating member or part 44 and on the oppositeside with an identical part 44','the latter functioning with thecooperating part 43 of the bar I for the reversed position. Thecooperating faces and bearing surfaces of the ends 49 and 4|, includingthe male and female bearing parts 43, 44, 44" maintain the two bars land 2 in alignment, take up the wear and assume the shearing forces orstrains ordinarily put upon the pivotal axis and the fastening boltfunctions merely as a means for holding the parts in cooperativeengagement and relation.

The outer end of the arm I is fastened in any suitable manner to thedoor frame 4. For example, as illustrated, a substantial or heavybracket 46 is illustrated having a flat plate 41 with openings thereinfor securing the bracket flat against the frame member. The plate 41 isreduced in width and has integrally formed therewith, an ear or jawmember 48 with a pintle 49 passing through the ear or jaw 48 and plate41 and functioning as a pivotal connection for the outer end of the barI. The plate 41 has an elevated or thickened part 50 in the vicinity ofthe jaw 48 for forminga bearing surface and providing the desiredclearance between the arm or bar I and the plate 41, the bar I havingits end flattened out, as indicated, at 5| with surfaces parallel to theplate. I

The holder is also provided with means cooperatively'related to thereversible bar 2 and the locking mechanism for absorbing shocks andtaking up undue strains which may be put thereupon during operation. Forthis purpose one of the members or arms I or 2 is provided with acushioning and yielding means permitting a limited amount oflongitudinal yielding in either direction when it is attempted to forcea door past the full open position in opening or in attempting to forcethe door in either direction when locked in stop position. In theparticular embodiment shown the bar I is provided with such means. It isformed in two parts an inner part 52 and an outer part 53, these twoparts having telescopic sections 52 and 53 respectivemakes a slidablefit with the bushing 54 and is' further reduced to form a stem 51 aroundwhich is disposed a compression spring 58, one end of the springengaging a washer 59 which in turn engages a pin 60 carried by and fixedto the stem 5?. The other end of the spring engages both the shoulder54' formed by the end of the bushing 54 and the shoulder 56' of thereduced cylindrical part 56, the outer diameter of the spring beinggreater than the inner diameter of the bushing 54. The hollowtelescoping part 53 is provided on the interior thereof with meansengaging the collar 59 on the opposite side from that engaged by thespring so that when the member 52 is moved to the right (Fig. 4) a forceis exerted upon the spring, the other end of the spring being engaged bythe shoulder formed by the reduced cylindrical part 55. In theparticular embodiment shown herein this means comprises a sleeve 63carried inside the hollow part 53' with one end of the sleeve engagingthe collar 59 andthe other end of the sleeve abutting the solid part ofthe member 53. The sleeve 63 is provided with grooves 64 foraccommodating the ends of the anchoring pin 69 and permitting therelative movement of the member 53 with respect to the member 52 (Fig.4). The bushing 541s provided with a skirt 66 in telescopic relationwith the enlarged part 52'. The parts of the bar I may be readilyassembled as follows:

The bushing 54 is inserted in position over the reduced cylindrical part56 of the telescoping part 52', then the spring 58 is inserted over thestem 5] and the collar 59 and pin 60 inserted in position with thespring engaging. the collar 59 at one end and engaging the shoulder 56formed by the reduced part 56 at the other end. Then with the sleeve 63inserted within the telescoping part 53' the telescoping part 52 isinserted into the hollow part 53 withthe collar 59 engaging the sleeve63 andthe pin 60 in registry with the slots 54 whereupon the bushing 54may be screwed home to form a part of the hollow telescopic part 53 withits shoulder in position to engage the spring 58 which, as abovedescribed, also engages the shoulder 55' formed by mechanism which isadapted to various uses of such mechanisms" and particularly" adapted towithstand rough and heavy usage. Withthe door in closed position. theplunger I8" rides upon the fiat surface of thetangII or end of the bar,but

when the door is opened to the desired extent,-

namely, when the face I of lug I5 abuts the door or plate 8 the plunger18 beingthen in-registry witlrthelockingrecess I9-formed in the tang IIis caused to enter this recess by the spring 22 and the door isthusretained in the open position untilthe plunger I 8- is withdrawnfrom the recess I 9. Thismay be done by grasping the handle I8 whereuponthe door may again be closed either partly or entirely. If it is desiredto render the automatic locking mechanism inoperative this may be doneby turning the plunger I8 to cause the pins 21 to rest within thenotches or niches formed in the head of the bushing 25, whereupon thedoor can be opened to its full extent without the automatic lockingmechanism coming into operation. As above indicated, the shock absorbingmechanism cooperatively functions with the stop lug I5, the automaticlocking mechanism including the plunger I8 and the strain or forcetransmitting means 43, 44, id to prevent undue strains and wear beingplaced thereupon by careless or inconsiderate door operators. Forexample, if it is attempted to open the door to a wider extent than thatprovided by the mechanism including the stop lug I5 the bar I isyiel-dingly extended in length, the spring 58 being compressed betweenthe collar and pin 59 and 60 and the shoulder 54 formed by the bushing54; and if it is attempted to close the door while the door isautomatically locked in the open position the mechanism similarly yieldsunder the influence of the spring mechanism, the spring 58 being thencompressed between the shoulder 56' formed by the reduced parts 56 and51 and the collar 59 which is prevented from movement by engaging theend of the sleeve 63, the pin 60 moving in the grooves 64 of the sleeve.This shock absorbing and yielding mechanism which forms a part of thearms-or bars, therefore, cooperatively functions with the locking meansand the strain transmitting means 43, 44, 44 to protect the door holderagainst injury from rough and careless usage and minimizes the Wearthereupon. Moreover, as above indicated, the holder is readily adaptableto either a right or left hand door with no modification in constructionthereof needed and with the single automatic locking mechanism equallyoperative in both adaptations to function with the shock absorbing meansand the strain transmitting means above described as forming a partthereof. For example, while in the particular embodiment illustrated inFig. 1 the door in opening swings counter-clockwise about its hinge 6the mechanism is equally applicable to a door opening by turning aboutits hinge in a clockwise direction. Fig. 6 shows in full lines theapplication shown in Fig. 1, while the dot and dash lines show therelation of the bar 2 with respect to the bracket I in the otherapplication referred to. Moreover, as above indicated, the adaptationfrom one character of door to the other is accomplished by disconnectingthe bar 2 from the bar I and from the bracket I, turning it about itslength through an angle of 180 so as to reverse its top and bottom facesand then securing it again to the bar I and the bracket 1, the bracket 1being still secured to the door with the automatic looking mechanismdepending from the under side of the bracket, while the automaticlocking mechanism,- the strain transmitting means at the juncture of thebars I and 2 and the shock absorbing means forming a part thereof,function in the same advantageous manner in either adaptation of theholder. In the limiting position, namely, with the stop I 5 inengagement with the plate 8, the restrainingarms I and 2 are still oilthe dead center, namely, they are disposed at an angle of less than 180on the closing side or next to the hinge 6, and accordingly the door maybe readily closed when the locking plunger I8 is withdrawn.
